Another abandoned project another muncaster

Hi All,
Well here is another abandoned project now resurrected from "under the bench". About time I got it finished.
Yes it's another muncaster from his excellent 1912 book. The simple line drawings from the book are not complete but within the book there is enough information to make the model.
This is my first two cylinder engine after 10 years of modelling. The machined/fabricated cylinders are arranged back to back on a central valve block. I do intend to make and fit the reversing valve.
The the photos reveal very much how it was the last time I worked on it. The oak box bed is extra deep to accommodate some pipework from the reversing valve.
More to come, hope it's of interest

Definitely interested and following along; I admire your ability to decipher the line drawings and machine the parts, I struggle with that particular element of our chosen hobby. I will take a look the book though   

Hi All,
Thanks for the post Sanjay. In reply yes the line drawings in the book are basic so I have done some metric  CAD work to help with the build.
Here is some more progress on the top end. The photo shows the entablature with the two alloy plummer blocks and brass bobbin bearings. These are copies of a pair in one of Jason's designs. I like the way he relieved the sides of the blocks leaving the bases a little wider.
The remaining photos show a simple jig which I used to assemble the crankshaft parts. The two spacers with locking screws accurately position the spacing of the double cranks. One double is clamped horizontal and the other set vertical with a tri square. They are glued with loctite 638 and then later pinned, so a real "belt and braces" job. Note the webs on the cranks, not included in original Muncaster drawings. I like webs from a practical as well as aesthetic viewpoint.
The engine is a little further on now with more to come

Hi All
Well here it is, all set up and running smoothly. Really pleased, it took some time but was well worth it.
Still a few things to do, adding the reversing block and parts, painting, final finishing etc. The flywheel is an old feed screw hand wheel, ok but I may change it for a cast spoked wheel around 60mm diameter. I'll see what I can find. More to come including a video but will be a while as other summer stuff is taking precedent.!!!!!

Well done.
And when it's finished, it's a small engine for a paddle steamer.

Yes, why not Michael. 
I remember going to Bristol many years and boarding the great eastern. I seem to remember that had two massive oscillating cylinders driving an overhead shaft.
Nothing like mine of course
Geoff

This has made a pleasing and compact engine of an unusual sort, nice little project to complete.  It's a pity that some sort of paddlewheels rather than a flywheel are difficult to arrange without entailing a great deal of extra work, but putting a spoked flywheel on it would be worthwhile I should think.

Hi All
Well some more progress, the photos show the addition of the reversing valve and also a new "spoked " flywheel. The latter was supplied by Forest Classics, it's a great casting which machined up really well.
I now have a you tube video of the engine running, "muncaster twin cylinder oscillating engine". Not running perfect as yet but some minor tweaking and gaskets etc. on final assembly should rectify any problems.
Sorry still not worked out how to upload videos.
More to come, intend to oak clad the cylinder and paint where appropriate.
Thanks for looking
Geoff

Looks great Geoff and runs nicely (I just watched the video here's the link, if you don't mind me putting it up on the site?)

Hi Sanjay,
Thank you for your comments and the video upload
Geoff

Works wonderfully
